Brief Summary
The objectives of the study were:
- 1.To assess the safety and tolerability of escalating doses of CINRYZE.
- 2.To assess the effect of an escalating dose algorithm for CINRYZE on hereditary angioedema (HAE) attack rates.
- 3.To assess the immunogenicity of CINRYZE.

Conditions
Outcome Measures
Primary Outcomes (1)
Number of Subjects With Adverse Events, Hospitalizations, Thrombotic Events, Treatment-emergent C1 INH Antibodies, Post-baseline Toxicity Grade Increases in Clinical Laboratory Parameters, and Post-dose Vital Signs Changes of Potential Clinical Importance
Events reported during the 3 month follow-up period are counted with the dose level at which they occurred.
12 to 24 weeks at each dose level
Secondary Outcomes (1)
Treatment Effect of Escalating Doses of CINRYZE on HAE Attack Rates
12 weeks at each dose level
Study Arms (1)
CINRYZE
EXPERIMENTALThere were 3 potential dose escalation steps: * Step 1: 1500 Units of CINRYZE (C1 inhibitor \[human\]) administered by IV infusion twice per week for 12 weeks * Step 2: 2000 Units of CINRYZE (C1 inhibitor \[human\]) administered by IV infusion twice per week for 12 weeks * Step 3: 2500 Units of CINRYZE (C1 inhibitor \[human\]) administered by IV infusion twice per week for 12 weeks

Eligibility Criteria
You may qualify if:
- To be eligible for this protocol, subjects must:
- Be ≥6 years of age and ≥25 kg body weight.
- Have a confirmed diagnosis of HAE with a documented history of swelling of the face, extremities, gastrointestinal tract, genitalia, or larynx and a history of at least one of the following:
- C1 INH gene mutation
- C4 level below the lower limit of the reference range
- C1 INH antigen level below the lower limit of the reference range
- Functional C1 INH level below the lower limit of the reference range
- Family history of HAE (i.e., grandparent, parent, sibling)
- Have a history of \>1.0 HAE attack per month (average) of any severity during the 3 consecutive months prior to screening while receiving the recommended CINRYZE dosing of 1000 Units every 3 to 4 days via intravenous injection.
- If an adult, be informed of the nature of the study and provide written informed consent before any study-specific procedures are performed.
- If a child, have a parent/legal guardian who is willing and able to provide written informed consent for the child to participate in the study (with assent from the child when appropriate).
You may not qualify if:
- To be eligible for this protocol, subjects must not:
- Have, as determined by the investigator and/or the sponsor's medical monitor, any surgical or medical condition that could interfere with the administration of study drug or interpretation of study results.
- Have a history of abnormal blood clotting or other coagulopathy.
- Be taking prescription anticoagulant medication.
- Have a history of allergic reaction to CINRYZE or other blood products.
- Have participated in any other investigational drug study within the past 30 days (other than CINRYZE protocols).
- Have received any blood products (other than CINRYZE) within 60 days prior to screening.
- Have any of the following laboratory values at screening:
- Hemoglobin \<8 g/dL
- White blood cell count \<2 x 10\^9/L or \>20 x 10\^9/L
- Platelet count \<50 x 10\^9/L or \>400 x 10\^9/L
- Serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) \>2.0 x the upper limit of normal
- Blood urea nitrogen and/or creatinine \>2.0 x the upper limit of normal
- Be pregnant or breastfeeding.

Limitations and Caveats
Per Changes in the Planned Analyses: The clinical presentation of disease manifestations and response to therapy are highly variable among patients with HAE and as such, the efficacy results from this study are presented in this report by individual participant in narrative summaries rather than as summary statistics. Thus, one outcome measure (Use of rescue therapy and/or other therapy for treatment of HAE symptoms) is not presented.
